A funny poem.

My grandfather in his youth 
Had a magic wish, to tell the truth.
He wanted to find a pot of gold,
That's in the bottom of а rainbow.
And when his granny was away
He took a mop and started way.
While he was reaching the rainbow's end,
He found only a pot of eggs.
Today he's in the 60-s age
And doesn't want to sit on a bench.
He wears boots, a coat, a cap,
And takes with him not a mop, but a map.
